Reasoned Opinion


In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Nature's Crops International submitted a request to the competent national authority in the United Kingdom to modify the existing maximum residue level (MRL) for the active substance thiacloprid in corn gromwell seeds. Furthermore, the competent national authority in Belgium compiled an application to modify the existing MRL for the active substance thiacloprid in radish. The renewal process for thiacloprid is currently ongoing; in 2015, the Committee for Risk Assessment concluded that the classification as Cat. 1B for adverse effects on development according to CLP criteria is warranted (H360FD). Considering that there is strong evidence that this active substance meets the cut‐off criteria for non‐approval defined in Article 4 of Regulation (EC) No 1107/2009, further risk management considerations have to be taken into account before a decision on the amendment of the existing MRLs is taken. The data submitted were compliant with the currently applicable legal requirement to derive MRL proposals for corn gromwell seeds and radish. The estimated exposure resulting from the residues of thiacloprid in corn gromwell seeds and radishes is not expected to exceed the toxicological reference values.
